@Lumage the window border is made up of sprites, not text. As far as 3D, it will be used to draw the active window in front of others, & when the active window changes, the "root" sprite (which all window sprites link to) of each window (active & former) will have the Z index adjusted through SPOFS. Users can also turn 3D off any time via the slider, at which point the effect will render in 2D.
